With over fifty years of optical experience dating back to Apollo Skylab and

BOULDER, Colo., February 20, 2015 – Bach Research Corporation has been awarded a contract from Ball Aerospace & Technologies Corp. to manufacture and deliver custom diffraction gratings and spares that will fly aboard two pollution monitoring missions.

“This builds on our 40-year relationship with Ball Aerospace and we couldn’t be more pleased with Ball’s continued confidence in Bach Research’s ability to supply critical components to support Ball’s space flight instrumentation,” said Bernie Bach, operations manager at Bach Research.

The components are being built for the Geostationary Environment Monitoring Spectrometer (GEMS) instrument for the Korea Aerospace Research Institute; and the Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument, a NASA Earth Venture mission. Both instruments are being built and designed by Ball Aerospace.

With over fifty years of optical experience dating back to Apollo Skylab and Voyager spacecraft, Bach Research Corp is a manufacturer of custom optical components and diffraction gratings for OEM, Aerospace Research, Astronomy and Spaceflight Instrumentation.

Ball Aerospace & Technologies Corp. supports critical missions for national agencies such as the Department of Defense, NASA, NOAA and other U.S. government and commercial entities. The company develops and manufactures spacecraft, advanced instruments and sensors, components, data exploitation systems and RF solutions for strategic, tactical and scientific applications.

Delivery of hardware

Feb 5, 2015

Bach Research is pleased to announce the delivery of spaceflight diffraction gratings and optics for two instruments that will fly aboard the NASA ICON Spacecraft. Under a contract with Praxis Inc, Bach delivered multiple sets of gratings and spares to be incorporated into the MIGHTI instrument which is built at the Naval Research Laboratory. Under a contract with UC Berkeley Space Science Laboratories, Bach Research also delivered custom UV Optics for the FUV instrument aboard ICON.

About ICON:The Ionospheric Connection Explorer, or ICON mission, is under development by NASA for flight in 2017. ICON will explore a swath of Earth's atmosphere where the weather close to the ground impacts the dynamic space environment above in unexpected ways.To study the connection between these space weather disturbances and Earth's weather, ICON will measure how motions in the lower atmosphere are transmitted into space. The lowest layer of the atmosphere -- the one we live in and where we experience weather -- is the troposphere. Above that is the stratosphere, the mesosphere, and the thermosphere. All of these are layers of the atmosphere made of neutral gas, which can move in reaction to the weather closest to Earth.

ICON will fly with four instruments. The Michelson Interferometer for Global High-Resolution Thermospheric Imaging, or MIGHTI, will observe the temperature and speed of the neutral particles. The Ion Velocity Meter will observe the speed of the charged particle motions, which may be very different from the neutral gas. Measurements of the particle density and composition are made by two spectrographic imagers: one, EUV, gathering extreme ultraviolet light, the other, FUV, gathering far ultraviolet light. These will be able to spot light emitted or scattered from particles in the thermosphere and ionosphere, which can then be translated into understanding just how many neutral and ionized particles are present, as well as what types of particles are predominant under different conditions.

BRC is moving

Jan 29, 2015

Bach Research Corp has announced it will be moving to a larger updated facility. The newly renovated 16,000 sq.ft. facility will house expanded testing labs, manufacturing area, ruling laboratories, clean room and dedicated diamond turning labs. The new

manufacturing capacity will allow Bach Research to broaden its custom solutions for it’s clients, in addition to offer 300+ different grating designs from it’s Master Catalog for OEM customers. The move should be complete in May 2015.Bach Research Corp manufactures custom optical components and diffraction gratings used in the UV to the LWIR. In addition to it’s commercial customers, Bach

Research has a proven spaceflight heritage of supplying one of a kind optical hardware flying aboard The Voyager Spacecraft to the James Webb Space Telescope.

From Boulder to Venus

December 2005

Venus Express, the first European Space Agency (ESA) mission to Venus was launched Thursday November 10th at 03:33 GMT from the Baikonur cosmodrome in Kazakhstan. Aboard the spacecraft is a custom optic: an echelle grating, manufactured by a local Boulder company, Bach Research Corp. Bach Research delivered two gratings in Sept 2004 for the ESA mission. The echelles represent an advance in grating technology since they were machined, not classically ruled. The echelle grating is an integral part of the Solar Occultation at Infrared (SOIR) instrument aboard the spacecraft. It will allow scientists to analyze Venus’s atmosphere by observing the sun through the planetÂ’s atmosphere. The instrument represents a new concept for compact instruments (3-5 kg) doing high-resolution near-IR spectrometry and scientists believe it could potentially be used for studying gases, such as CO2, in the Earth’s atmosphere, as well as monitoring sources of pollution, such as industrial activity and power generation. This new compact instrument is being considered as a building block in a ground network for CO2 monitoring in Europe.

Bach Research expands Grating Laboratory

July 21, 2004

Bach Research announced the addition of three ruling engines to their existing ruled and holographic grating laboratories. This addition brings the total number of ruling engines to four two engines for high-line density gratings and two specifically geared for echelle gratings. "The acquisition of these engines enhances our capability to continue to provide the outstanding services to the photonics community, and is in line with Bach Research's strategic plan for long term growth", said Kirk Bach, Vice President and Director of the Ruling Lab. All four ruling engines are interferometrically controlled and already have a proven track record within the industry. Bach Research is able to rule gratings as large as 300mm x 450mm on both plano and non-plano surfaces.

In related news, Bach Research has also added it's second diamond turning center and a fourth high vacuum coating chamber to keep in step with demand for services.
